Abstract
Described are methods, systems, and apparatus, including computer program products for de-duplicating access control lists (ACLs). A first ACL associated with a first computer file is received. A first checksum based at least in part on the first ACL is calculated. One or more directory entries based on the first checksum are retrieved from a de-duplication directory, wherein each directory entry of the one or more directory entries comprises a reference to an ACL and a name comprising the first checksum. A directory entry of the one or more directory entries is identified that references a second ACL that specifies the same permissions as the first ACL. A reference to the second ACL of the directory entry is added to the first computer file.
